EEG slow waves in traumatic brain injury: Convergent findings in mouse and man

open access: yesNeurobiology of Sleep and Circadian Rhythms, 2017
Objective: Evidence from previous studies suggests that greater sleep pressure, in the form of EEG-based slow waves, accumulates in specific brain regions that are more active during prior waking experience. We sought to quantify the number and coherence

Sleeping at the switch

open access: yeseLife, 2021
Sleep slow waves are studied for their role in brain plasticity, homeostatic regulation, and their changes during aging. Here, we address the possibility that two types of slow waves co-exist in humans.

Slow waves on long helices

open access: yesScientific Reports, 2022
Slowing light in a non-dispersive and controllable fashion opens the door to many new phenomena in photonics. As such, many schemes have been put forward to decrease the velocity of light, most of which are limited in bandwidth or incur high losses.

Cortical and subcortical hemodynamic changes during sleep slow waves in human light sleep

open access: yesNeuroImage, 2021
EEG slow waves, the hallmarks of NREM sleep are thought to be crucial for the regulation of several important processes, including learning, sensory disconnection and the removal of brain metabolic wastes.

Thalamic activity during scalp slow waves in humans

open access: yesNeuroImage, 2022
Slow waves are major pacemakers of NREM sleep oscillations. While slow waves themselves are mainly generated by cortical neurons, it is not clear what role thalamic activity plays in the generation of some oscillations grouped by slow waves, and to what ...

Nitric Oxide Is Essential for Generating the Minute Rhythm Contraction Pattern in the Small Intestine, Likely via ICC-DMP

open access: yesFrontiers in Neuroscience, 2021
Nitrergic nerves have been proposed to play a critical role in the orchestration of peristaltic activities throughout the gastrointestinal tract. In the present study, we investigated the role of nitric oxide, using spatiotemporal mapping, in peristaltic

Local and Widespread Slow Waves in Stable NREM Sleep: Evidence for Distinct Regulation Mechanisms

open access: yesFrontiers in Human Neuroscience, 2018
Previous work showed that two types of slow waves are temporally dissociated during the transition to sleep: widespread, large and steep slow waves predominate early in the falling asleep period (type I), while smaller, more circumscribed slow waves ...

Neurophysiology of Avian Sleep: Comparing Natural Sleep and Isoflurane Anesthesia

open access: yesFrontiers in Neuroscience, 2019
Propagating slow-waves in electroencephalogram (EEG) or local field potential (LFP) recordings occur during non-rapid eye-movement (NREM) sleep in both mammals and birds.

Na+/Ca2 + Exchange and Pacemaker Activity of Interstitial Cells of Cajal

open access: yesFrontiers in Physiology, 2020
Interstitial cells of Cajal (ICC) are pacemaker cells that generate electrical slow waves in gastrointestinal (GI) smooth muscles. Slow waves organize basic motor patterns, such as peristalsis and segmentation in the GI tract.

MODELING OF SOUND WAVE PROPAGATION IN THE SOLAR CORONA

open access: yesСовременная наука и инновации, 2023
In this paper we aim to simulate the propagation of magnetosonic waves in the solar corona by modeling the decay of a wave packet due to the thermal misbalance and the dispersion effect.
